This study was conducted to evaluate the persisting Covid-19-related symptoms of the cases included in our study and to assess their cardiac findings to determine the impact of Covid-19 on children’s cardiovascular health.

In this study, 121 children between the ages of 0– and 18 with Covid-19 were evaluated based on their history, blood pressure values, and electrocardiography and echocardiography results. These findings were compared with the findings of the control group which consisted of 95 healthy cases who were in the same age range as the study group and did not have Covid-19. The results were evaluated using the statistics program, SPSS 21.

There was no significant difference between the study group and the control group in terms of age, weight, and body mass index. The clinical symptoms (chest and back pain, dizziness, headache, palpitation, fatigue, shortness of breath, loss of balance, coughing) of 37.2% of the cases persisted for at least 1 month after Covid-19 recovery. Statistically significant differences were found in systolic blood pressure, left ventricular ejection fraction, relative wall thickness, and tricuspid annular plane systolic excursion.

The continuation of some cases’ clinical symptoms post-recovery indicates that long Covid infection can be observed in children. The fact that statistically significant differences were observed between the echocardiographic parameters of the study and control groups suggests that Covid-19 may have effects on the cardiovascular system. To shed light on the long Covid cases among children and the infection’s cardiac impacts, it would be beneficial to conduct more comprehensive studies on this matter.

进行这项研究的目的是评估我们研究中包括的病例持续存在的与 Covid-19 相关的症状，并评估他们的心脏检查结果以确定 Covid-19 对儿童心血管健康的影响。

在这项研究中，根据他们的病史、血压值以及心电图和超声心动图结果对 121 名 0 至 18 岁的 Covid-19 儿童进行了评估。将这些发现与对照组的发现进行了比较，对照组由 95 名与研究组处于同一年龄范围且没有 Covid-19 的健康病例组成。使用统计程序 SPSS 21 对结果进行评估。

研究组和对照组在年龄、体重和体重指数方面没有显着差异。在 Covid-19 康复后，37.2% 的病例的临床症状（胸背痛、头晕、头痛、心悸、疲劳、气短、失去平衡、咳嗽）持续至少 1 个月。在收缩压、左心室射血分数、相对壁厚和三尖瓣环平面收缩期偏移方面发现了统计学上的显着差异。

一些病例康复后临床症状的延续表明，在儿童中可以观察到长期的Covid感染。在研究组和对照组的超声心动图参数之间观察到统计学上的显着差异这一事实表明，Covid-19 可能对心血管系统有影响。为了阐明儿童中长期存在的 Covid 病例和感染对心脏的影响，对此事进行更全面的研究将是有益的。
